This is clunky phrasing — it’s probably wrong to say it was ‘less crucial’. The fact that companies were willing to invest a lot of money in administrative type roles says a lot about their importance to the way businesses used software in the first decade of the millennium.
What I’m trying to get at is that even a decade ago (possibly even 5 years ago), there was a distinct difference between software development and the way in which it was administered and maintained. This change is a just a small component of wider trends in the way we use software, largely driven by changes in user expectations and behavior (mobile etc.), and incremental improvements (innovation on a small scale, I guess) within software development itself.
